New Nepros 3/8″ Ratchet is Stronger, Smaller, Lighter

Nepros NBR390A Ratchet Hero

Nepros has updated their 3/8″ ratchet, launching the new NBR390A.

The new Nepros NBR390A ratchet, featuring 90T gearing, full-polish, and 7″ overall length, is described as being the world’s finest aesthetic and functional.

Nepros NBR390A Ratchet

The NBR390A ratchet looks a lot like Nepros’ NBR390 ratchet, which launched 10 years ago in 2012.

Nepros NBR390A Ratchet vs NBR390 Head Size

Compared to the NBR390, the new NBR390A is said to be 10% lighter. It also has a slimmer head, with 4mm shaved off the teardrop-shaped head width.

In addition to being slimmer, the NBR390A ratchet’s head length has also been reduced slightly, allowing for better access in tight spaces.

Some of the weight savings comes from the new hollowed-out handle design, with a cross-section showing additional material removal.

Nepros says they achieved both best weight balance and lightness.

The ratchet’s internal mechanisms are also different, with the upgraded gear pawl engaging with 8 teeth instead of 7, for even greater strength.

Lastly, Nepros updated the gear component, which weighs 40% lighter than the previous model. Additionally, Nepros says that inner stress is dispersed by round-machining.

Dimensions: 180mm (~7″) length, 26mm (~1″) width, 14mm (~0.55″) height.

Ratchet Gear: The 90T gearing creates a 4° minimal swing angle.

A repair kit, NBR390A-K will be available.

Price: ¥12,600

I ordered a test sample from Amazon Japan. I’ve ordered from there before with great experiences each time.

At the time of this posting, the Amazon JP price is ~¥13,625 including shipping, which comes out to ~$95 USD with the current exchange rate. Foreign transaction fees could apply. Amazon Japan also allows for checkout in USD, which comes out to ~$96.

Nepros Tools’ price is $119 + $19.90 shipping.

    The only USA source that I could find – sells it for $118

        I’ve found that seller (DRPD) to have been up and up with the few dealings that I have had with them. They sometimes have holiday promotions, stock PB Swiss, and other premium European and Japanese Brands. I found out about them via one of your reader’s comments.

          The last things I bought from them were Ko-Ken – double universal joints. I think that style may be unique to Ko-Ken:

            I guess that a double-ended universal joint is sort of like a short version of the double universal extension bar from Vim:

            https://vimtools.com/product/dse68/

            There are also bent extension bars made by Stahlwille

            https://chadstoolbox.com/12250001-stahlwille-1225-3-8-drive-special-extension/

            Both are meant to help you clear obstructions.

            I just ordered those Vim double ended extensions. Mac Tools also sells a 6 piece set, with some additional sizes, https://www.mactools.com/products/smxvd6elq
            And Matco also has the 1/4, 3/8, and 1/2″ .
            I suspect these all may be rebranded Vim tools. I would love the 6 piece set from Mac, but $460 is a little much for a Novelty. The 3 Vim items ran me right around $100.

          I’ve also had great luck with DRPD. Bought some Koken sockets, extensions and some USAG stuff during a recent sale.

          Heard about them on Garage Journal where they will post deals and updates occasionally.

    Speaking of Nepros, Stuart, did you ever manage to find out from Nepros if their “gold” finish was actual gold or was TiN plating? I remember we discussed that a while back but I don’t think the question was ever definitively answered.

    Thats interesting. for all that work they didn’t really get much out of it.

    I don’t know that I’d like that hollowed handle but it would be interesting – more so if it’s thicker than a basic 3/8 ratchet handle without a comfort overmold. which I would think would be cheaper and lighter.

    IE plastic overmold of a thinner solid steel shaft – for equal overall diameter – would be lighter than their machined hollow handle. Would it feel better, work better – not sure. Bet it runs smooth. Do they make them in Quick Release?

      That model is quick release. Look at the hole in the anvil.

      Have you ever held one of the Dewalt ratchets with the large flat/oval handle, like the ones that come in the mechanics sets they sell at HD? Those are solid steel and they weigh a ridiculous amount. I wish they would hollow them out.

      Vampire is another Japanese company which makes pliers similar to Engineer. A few of my favorite Japanese tools off the top of my head:
      Silky saws
      Ko-Ken mechanic’s tools
      Mitutoyo measuring instruments
      Olfa utility & craft knives
      Wood Owl drill bits
      Tajima caulk gun

        Oh, and Japanese gardening tools are also generally excellent. Even the cheap brands for things like cultivators, sickles, weeders, etc, are usually very good quality for the money. Regarding specific recommendations there’s the “hori-hori”, sort of a combination knife and trowel which is super handy since you can use it to dig, chop roots, open bags of mulch/fertilizer/etc with just the one tool. The “ika hoe” is another tool that is really good, it’s been widely copied but the Japanese ones with the one-piece forged steel head are much better than the welded-together ones you find at big box stores and they’re reasonably priced too. For example the ones by Kusakichi are amazing value at only $25.

            I couldn’t agree more about the Silky pruning & outdoor saws. First time you use one of those is an epiphany.

            And speaking of sharpening tools I am a big fan of Naniwa synthetic waterstones, especially the Professional line (formerly called Chosera). They cut fast, they have great feel.

      I have a few “fujiya” pieces (pliers, cutters) that are pretty good.
      My favorites are “goot” for soldering and accessories.

      I bought a 24″ cable cutter from Japan made but some cutlery company there because all I could find in the west were either too cheap or too expensive. The name escapes me now but it’s pretty good for 1/2″ cables where Chinese quality straggles.

    Personally I don’t see the reasoning to feature a tool that has no US Distributors to order from? Japan made, great! Professional Quality great! Pricing not so great but if you make your living using tools then maybe worth it. Warranty? Not so great. Ordering and obtaining the tools? Not so great. Example: There is a small village in the Swiss Alps that makes the worlds finest screwdrivers! Nearly unbreakable and lifetime warranty replacement for any reason! The “rub”is you have to fly to the country and rent a dog sled and team to purchase these screwdrivers!

      Look at my first post for DRPD – one of the USA distributors. I think that Stuart cited Amazon.jp – because their pricing was low – perhaps beacuse of the dollar’s strength versus the Yen (alto the Japanese central bank has been selling of dollars to bolster the Yen).

      BTW – I found a maker (blacksmith) of carving tools in Lithuania – and bought some of his wares when I was visiting – but he does not market outside his own area.

      Also, no different than posting about a tool that is available in Europe and other parts of the world, by a main MFR, yet we do not have it here. With Makita, Bosch and other brands, we often here about tools we don’t have available here and wonder if we will get it at some point or will we get it at all.

    Other than this Ratchet (not counting the older model, because they’re basically the same model, revised, not a different product.) has ToolGuyd ever covered anything else by Nepros? The name sounds really familiar. Were they the ones that made that incredible gyroscopically balanced precision screwdriver that was on Kickstarter or something like that? I know it was someone who designed that one to be a limited run, but the tools seem to be cut from the same cloth design-wise.

    And speaking of design… Is anyone else kinda taken by how much like jewelery these little ratchets appear to be? Not to gush over looks, it’s just, is anyone else seeing how much detail they put into exact curves, and how elegant the design is? Almost like they wanted it to look even more expensive than it ends up being?

    I’m finding it hard to put into words. Aesthetics are not my forte when it comes to language. I will be checking the Nopros site for what else they make, but I could have sworn Stuart did a writeup on a different tool from them a while back… with equal praise for the aesthetics to boot…

    I have the previous model, which I love.

    I got it 5+ years ago from https://frankstools.com/products

    I had got a Nepros 1/4 ratchet and socket set and a Koken 1/2″ set + some other individual tools; all very nice.

    I have not order anything from him in many years but at the time, prices and service were great. For stuff you do not see on his website, you can email him and he can tell you if he can get it plus price.

    ****I was checking some items and everything I checked is out of stock, not sure what the deal is.

    so I sit corrected – it is a QR style ratchet. I like it.

    For the dollars there are alot of other products that are in my opinion easier to get hand on and easier to get repaired. but of similar quality – 95 dollars is going to be a bit hard to beat. I mean new a MAC is going to be more – same with Snap On, and I figure the Stahlwille in your hand in the US will also be more.

    so interesting. The SK was cheaper and I bet you can find one – though they aren’t made anymore. but it wasn’t QR.

      Just my opinion but when you use one, it feels nice in your hand. Very little drag, smooth and quality made. Is it the best, I can’t say, but definitely a premium, high quality ratchet.

      If you get one, you will not regret it. Myself I can’t say but I have heard others say that it is better than their Snap On or other premium ratchet.

      I already received mine too. I sprung an extra few dollars for priority shipping.

      I have to be careful with multi-item orders. If they ship products separately, the shipping fees will go way up. I changed the color of two SKUs (package opener and scissors), and my shipping fees were almost halved.

    I know I’m necroposting here, but I recently picked up a Nepros NBR390X at the Factory Gear shop on Tennozu Isle in Tokyo. With exchange rates, tax rebate, and a sale working out in my favor, I paid about $90 USD. While it is a bit steep, I wanted a souvenir with a bit more meaning and utility than a refrigerator magnet shaped like mt Fuji or a bullet train.

    I’m impressed with the quality, lightness and ergonomics of the ratchet, as well as the compactness of the ratchet head.
